No but light_groups does seem a good work-around, if it's okay.  It could be
difficult (impossible?) getting it right if animated clouds were used since
the shadow changes would possibly need counteracting in the light used for
that media only.
I didn't see anything wrong with using the planes in place of polygons, no
shadowing.  I just now realized the translation was being done twice for the
plane.  Hastily checking out pov script is like that.
